A signal control system is developed along an arterial in Hiroshima city from the viewpoint of a deterministic control for traffic flow dynamics. The signal control system of the congestion length is described by a nonlinear time-varying discrete dynamic system and synthesized by using the feedback control based on the volume balance at each signalized intersection. Two signal control algorithms are presented to balance congestion lengths which cross each other on a road. These control algorithms are such that the sum of congestion lengths along each approach is minimized. The signal control system is developed systematically according to the procedure from the road analysis to the simulation. From the comparison of congestion lengths between measurement values controlled by a pattern selection method such as the MODERATO and simulation values controlled by the proposed signal control algorithm, it is confirmed that the signal control system and its development procedure work effectively along the Route 2 in Hiroshima city.
